Water quality sampling and storing device for environmental monitoring

Abstract

The invention particularly relates to a water quality sampling and storing device for environmental monitoring. The device comprises a sampling mechanism and a storage mechanism, wherein the samplingmechanism comprises a hand rod, a suspension plate, hand rod lug plates, a bearing, a shaft rod, a hose, a sampling box, an electric cylinder controller, a storage battery I, a signal receiver, a partition plate, a supporting plate, an electric cylinder, a sliding block, a rotating rod and a shear fork lifting mechanism; the sampling box is fixedly connected to the middle of the lower surface of the suspension plate, a pair of hand rod lug plates is fixedly connected to the middle of the upper surface of the suspension plate, and the shaft rod is fixedly connected between the hand rod lug plates; and the shear fork lifting mechanism is arranged in the middle of the rotating rod. Water at different depths can be sampled, the sampling mechanism is placed in the water through the hand rod, the difficulty caused to sampling work due to the complex water bank environment is solved, use is convenient, a collected water sample can be temporarily stored, and the device is suitable for field work.

Description

technical field [0001] The invention belongs to the field of water quality monitoring, in particular to a water quality sampling and storage device for environmental monitoring. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. The scope of monitoring is very wide, including unpolluted and polluted natural water and various industrial drainages. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, chromaticity, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand etc.; the other category is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides. In order to objectively eval...

AI Technical Summary

Problems solved by technology

[0004] In the process of monitoring, it is necessary to sample and monitor the water body. Most of the traditional sampling tools are artificially entered into the water body for sampling. The traditional sampling method is extremely inconvenient and has too many restrictions. For some complex waterfront environments, Manual sampling is very difficult; therefore, there is an urgent need for a device that can be applied to water sampling in the field environment
